, DRAG-SAW FRAME.

SPECIFICATION-forming' part of Letters Patent N o. 733,749, dated July 14, 1903.

Application filed February 11, 1903. Serial No. 142,829. (No model.)

To fir/ZZ whom t may concern..-

Be it known that I, EDWARD E. REDFIELD, a citizen of the United States, and a resident of Grants Pass, in the county of Josephine and State of Oregon, have invented a new and Improved Drag-Saw Frameof which the following is a full, clear, and exact descrip-v tion.

This invention relates to a frame adapted to be engaged with and sustained on a log or other timber and to carry an engine and dragsaw in position for operation to saw the log. The saw and engine may be of any form desired, but concerning the engine I prefer to employ the apparatus disclosed in Letters Patent of the United States No. 679,637, granted to me on the 30th day of July, 1901, for an improvement in engines.

This specification is a specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure l is a plan View of the invention, showing the operation of theengine and saw in full lines; and Fig. 2 is a side view of the invention and indicating the operation of the engine and saw in dotted lines.

The frame comprises a main portion which is essentially rectangular in outline and is made up of side rails a, with cross-braces b, respectively, at its rear and middle portions, and diagonal braces c, such parts being arranged in any suitable manner to give a maximum degree of strength and rigidity to the frame. A stout end beam d is arranged to work in conjunction with the rear ends of the side rails a to hold the engine, which is indicated by the letter e in the drawings. The engine is provided with trunnions e', which are rockably held in the parts a and d', preferably by forming notches in these parts, which serve as bearings for the trunnions. Two engines may be employed simultaneously, or one engine may be employed and used at either side of the apparatus, as may be convenient or desirable. The pist0n-rod of the engine carries the saw, which is indicated by the letter f, and the saw works with the log (indicated at g) in the usual manner.

The front'extremities -of the side rails a are turned downward to form spurs a', which engage the log, as shown best in Fig. 2, and which are braced against the rails a by struts a2, as shown. A transverse front beam h of suitable construction is mounted rockably in the front ends of the railsV a and is provided at one end with'a notched sector h', adapted to be engaged by a dog h2, carried on one of the side rails a, so as to hold the cross-beam h at any desired axial adjustment. Sliding in the cross-beam h and disposed longitudinally of the frame is a hook t, the front end of which is curved downward and terminates in a strut arranged to engage the log at the side opposite that engaged by the spurs a'. The hook 1l has its shank ratcheted, as indicated, and a pawl h3, carried on the crossbeam h, Works with the ratchet-teeth, this pawl being pivoted at its forward end and having its rear end engaged with the hook, so that movement of the hook rearward relatively to the frame will not be prevented, but 4 .raising the rear end of the frame the crossbeam 7L and pawl h3 are caused to ride forward on the hook, and then as the pawl takes hold on the hook the entire frame will be sustained on the log and out of contact with the ground. This not only enables me to adjust the frarneto the most convenient position, but it also avoids the necessity of using the ground directly as alsup'port for the machine, which use would be disadvantageous in case the ground were uneven or obstructed by stumps or the like. When the parts have been adjusted as desired, the cross-beam h is locked by engaging the dog h2 with the seetor 71..

Various changes in the form, proportions, and minor details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie Within the scope of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent* 1. A drag-saw frame, comprising a frame proper adapted to engage its front portion with a log, a cross-bar roekably mounted in the frame, a hook sliding in the cross-bar, and means for adjustably holding the hook.

2. A drag-saw frame, comprising a frame proper adapted to engage its front end with a log, a cross-beam rookably mounted in the frame, a hook adjustably held in the crossbeam, and a device for adj ustably holding the cross -beam stationary with respect to the frame.

3. A drag-saw frame having side rails, connections between them, a cross-bar having its ends rockably mounted in the side rails, a dog slidably mounted in the cross-bar intermediate its ends, and means for adjustably holding the dog.

4. A drag-saw frame having side rails, conneetions between them, a cross-bar having its ends rockably mounted in the side rails, a dog slidably mounted in the cross-bar intermediate its ends, means for adjustably holding the dog, and means for adjustably holding the cross-bar against rocking.

5. A drag-saw frame having side rails bent downward at their front ends and formed with spurs to engage the log, and a dog located between the side rails to coact with the spurs.

6. A drag-saw frame having side rails and an end beam extending across them and hav- :ing its ends bent to extend alongside of the respective side rails to form engine-seats.

In testimony whereof I have signed my name 1o this specification in the presence of two subscribing witnesses.

EDWARD E. REDFIELD.
